Hello Nate or someone,
I really love spine, and i think that its super cool. Im using spin with unity 4.2 and it works perfect.
But now to the point, in version of Unity 4.3 will be native support of 2D, and we planing that our bigger one project will be maded in "official 2D". My question is, are you planing make Spine compatible with that official 2D?
Thank for reply Spide 
I don't believe there is a reason that Spine would not be compatible with 4.3. It will continue to work as it does now. Since Spine uses regular GameObjects, you'll be able to put Spine animations in your Unity 4.3 scenes like normal. We will be looking at what we could do to better integrate with 4.3 features, such as the built-in texture atlases.
That's right. If you notice the videos, Unity 4.3's 2D support is mostly very very nice workflow (and performance?) improvements for working with 2D assets and 2D game rules. The engine and rendering is still 3D and Spine's current setup will work just fine.
I wish we knew more about how their atlasing system works though.
Spine is compatible with 4.3, however its GameObject lacks the sorting layer setting the 4.3 sprites have. So, 4.3 sprites will be automatically drawn over the Spine animation.
The workaround is to set the 4.3 sprites on a certain layer, but that defeats the purpose of layer ordering.
I hope you guys can find a way of using 4.3 sprites for animations in the future.
PS: There's also this warning "Assets/spine-unity/Assets/Spine/Editor/SkeletonDataAssetInspector.cs(49,34): warning CS0618: UnityEditor.EditorGUIUtility.LookLikeInspector()' is obsolete:LookLikeControls and LookLikeInspector modes are deprecated.'"
I found no issues related to it so far.
Are you beta testing 4.3?
I don't think there's much Nate can do to support it while he has no access to 4.3 itself.
I suspect the sorting layers rely on them using the new Sprite component instead of meshes. I wonder how they'll work though.
Thanks for trying it out rmViper. Will look into it once I can play with 4.3.
